Modern digital multimeters (DMMs) are user-friendly, accurate, and safe — when used correctly! Reading voltage is simple, but measurements must be properly interpreted. With a clamp-on DMM, accurate ...

While using a digital multimeter to diagnose electrical problems on customers’ equipment, I frequently hear the comment, “I’ve got one of those multimeter things, but I never learned how to use it.” ...

Depending on the earthing configuration of the network, the instrument also uses multiphase measurements to calculate the impedance of the neutral conductor, enabling it to reveal defects that could ...

In the previous article in this series, we looked at bridge circuits used to measure impedance. Now, let's look at some more (simple) math. The scaled bridge voltage and current, v vx and v ix ...

Keysight Technologies today introduced three low-frequency options for its E4982A LCR meter. With these new options, the E4982A is suited for RF inductor, coil, and EMI filter manufacturers that are ...

Maintenance professionals are constantly being deluged with new models, new manufacturers, and new functionality in handheld digital multimeters. Safety features are perhaps the most critical factors ...
